Description
本発明は圧力板を使う切削インサート用ツールホルダーのクランプアセンブリに関するものである。
The present invention relates to a clamp assembly for a tool holder for a cutting insert using a pressure plate.
金属切削のための機械加工、とくに旋削用作業で使用されるツールホルダーにおいて、切削インサートに加えられるクランピング力が足りないため加工中にポケット内で切削インサートの微細な動きによって寿命が低下されたり、時おり破損される場合が発生する。また切削中に発生されたチップは高圧力でクランプに突き当てられクランプに過多な磨耗を発生させその寿命を急速に減少させる。そのような問題点を解決するために硬質の圧力板が結合されたクランプを使うツール
ホルダーが提案される。
In tool holders used in machining for metal cutting, especially in turning operations, the clamping force applied to the cutting insert is insufficient, and the life of the tool holder may be reduced due to minute movement of the cutting insert in the pocket during machining. Occasionally, damage may occur. Further, the chip generated during cutting is abutted against the clamp with a high pressure, causing excessive wear on the clamp and rapidly reducing its life. In order to solve such a problem, a tool holder using a clamp combined with a hard pressure plate is proposed.
しかし従来に使用されたクランププレートは別途のスクリューや連結板を使ってクランプに結合されているため、造作が不便で部品数が増加されるだけではなく、クランプに別途のねじタップの加工が必要になるため加工費が増加されタップ加工部位が脆弱になって破損の問題点があった。またクランプ
プレートの回転発生に対し脆弱な構造上の問題があった。
However, since the clamp plate used in the past is connected to the clamp using a separate screw or connecting plate, not only is the construction inconvenient and the number of parts increased, but a separate screw tap must be processed for the clamp. Therefore, the processing cost is increased, and the tapping site becomes fragile, causing a problem of breakage. There was also a structural problem that was vulnerable to the rotation of the clamp plate.
本発明は簡単な構造を持つ加圧板を使うことによって優秀なクランピング力を持ちながら、加圧板の交換が容易なクランプ

Including a front convex part, a rear convex part formed on the rear part of the fuselage and extending downward, and a bridge part connecting the front convex part and the central part of the fuselage; and the pressure plate described above, The front projection is inserted into the expanded cylindrical cavity, the bridge is inserted into the canyon, and the pressure plate is coupled to the clamp.
本発明の実施例によったクランプアセンブリは加圧板の前方ノーズ部が上部面から下部面に向けて傾斜した勾配面を含めるが、後方端部は垂直平担面を含めることができる。 The clamp assembly according to the embodiment of the present invention includes a sloped surface in which the front nose portion of the pressure plate is inclined from the upper surface toward the lower surface, but the rear end portion may include a vertical flat surface.
本発明の実施例によった加圧板は拡張された内側空洞部の上部面枠に突出補強部が形成されることができる。 The pressure plate according to the embodiment of the present invention may have a protruding reinforcing part formed on the upper surface frame of the expanded inner cavity.

In the tool holder assembly (10) of FIG. 1, a cutting insert (300) with a central hole (301) is clamped and assembled to the tool holder (500) by a clamp (200). Typically, the insert (300) is mounted on a shim plate (400) that is secured to the tool holder (500) by a screw (410).

図5及び図6は本発明の第1実施例によった加圧板をそれぞれ異なる角度で表した斜視図であり、図7はそれの平面図である。上記の加圧板(100)は切削インサートをツール ホルダー
ポケットに固定するためのクランプに使われるものでおり、上部面(110)、下部面(120)、前方ノーズ部(130)及び後方端部(140)を持ち、拡張された内側空洞部(151)を持ちながら峡谷部(152)によって後方に開放され、上記の上部面と下部面が成す厚さ方向に延びたキーホール形グルーヴ(150)を含める。圧力板は超硬材質になって容易に磨耗されなく長時間の使用が可能なようにする。また圧力板はクランプの加圧力がインサート上面の広い面積を強く押し付ける力を伝達する。
5 and 6 are perspective views showing the pressure plates according to the first embodiment of the present invention at different angles, respectively, and FIG. 7 is a plan view thereof. The pressure plate (100) is used as a clamp for fixing the cutting insert to the tool holder pocket.The upper surface (110), the lower surface (120), the front nose (130) and the rear end ( 140), and the keyhole-shaped groove (150) extending in the thickness direction formed by the upper surface and the lower surface is opened rearward by the canyon (152) while having the expanded inner cavity (151) Include. The pressure plate is made of super hard material so that it can be used for a long time without being easily worn. Further, the pressure plate transmits a force by which the pressing force of the clamp strongly presses a wide area of the upper surface of the insert.
クランプ アセンブリはクランプの前方凸部(210)が加圧板の拡張された円筒形空洞部(151)に挿入され、クランプのブリッジ部(240)が加圧板の峡谷部(152)に挿入されて組立結合される。 The clamp assembly is assembled with the forward projection (210) of the clamp inserted into the expanded cylindrical cavity (151) of the pressure plate and the bridge portion (240) of the clamp inserted into the canyon portion (152) of the pressure plate. Combined.
加圧板において、前方ノーズ部(130)は上部面(110)から下部面(120)に向けて傾斜した勾配面(131)を形成して加工中に発生されたチップが円滑に排出されるようにして、また後方端部(140)には垂直平担面(145)を含めることができる。加圧板は拡張された内側空洞部(151)の上部面(110)枠に形成された突出補強部(115)を持つことによって構造的剛性を補強し、加圧力がインサートの上面に比較的に均一に伝達されるようにする。なお、加圧板は後方端部(140)に隣接した下部面(120)に峡谷部(152)を横切って形成されたピン収容部(125)を備えることができる。 In the pressure plate, the front nose part (130) forms a sloped surface (131) inclined from the upper surface (110) to the lower surface (120) so that chips generated during processing are smoothly discharged. In addition, the rear end (140) can include a vertical flat surface (145). The pressure plate reinforces structural rigidity by having a protruding reinforcement (115) formed on the upper surface (110) frame of the expanded inner cavity (151), so that the applied pressure is relatively low on the upper surface of the insert. Ensure that it is transmitted evenly. The pressure plate can include a pin accommodating portion (125) formed across the canyon portion (152) on the lower surface (120) adjacent to the rear end portion (140).
上記のクランプ(200)の胴体底面部には加圧板(100)の垂直平担面(145)に対応する垂直支持面(225)が設けられるが、垂直平担面(145)と垂直支持面(225)が接触されることによって加圧板の回転が防止されブリッジ部に加えられる回転力を軽減することができる。上記の加圧板(100)の突出補強部(115)は上記のクランプの胴体前方部の下面の前方凸部(210)の周りに接触する。 A vertical support surface (225) corresponding to the vertical flat surface (145) of the pressure plate (100) is provided on the body bottom portion of the clamp (200), but the vertical flat surface (145) and the vertical support surface By contacting (225), rotation of the pressure plate is prevented and the rotational force applied to the bridge portion can be reduced. The protruding reinforcing portion (115) of the pressure plate (100) contacts around the front convex portion (210) on the lower surface of the front portion of the body of the clamp.
上記のクランプ(200)はブリッジ部(240)に横切って形成されたピン挿入ホール(241)が設けられることができる。クランプ アセンブリは結合ピン(245)をさらに含め、上記の結合ピン(245)がピン挿入ホール(241)に挿入されると同時に、ピン収容部(125)に収容されることで加圧板が一体化されたクランプ アセンブリが結合されることができる。通常的に結合ピン(245)は一字型のスプリング鋼で構成されピン挿入ホール(241)に弾性的な結合が可能にする。 The clamp (200) may be provided with a pin insertion hole (241) formed across the bridge part (240). The clamp assembly further includes a connecting pin (245), and the connecting pin (245) is inserted into the pin insertion hole (241), and at the same time, the pressure plate is integrated by being received in the pin receiving portion (125). Clamped clamp assemblies can be combined. In general, the connecting pin (245) is formed of a single-shaped spring steel and enables elastic connection to the pin insertion hole (241).
本発明はクランプと圧力板が1個の結合ピンによって簡単に結合される構造でおり、スクリュー等の別途の固定器具なしに造作が簡単で且つ部品数が縮小される効果がある。また脆弱しやすいクランプの前方凸部がブリッジ部によって補強されるため、使用寿命が多いに増加される効果がある。なお、圧力板の後方端部が垂直平担面で形成されクランプ内で回転されないよう防止され、ブリッジ部に加えられる回転力を軽減する効果がある。また突出補強部は加圧板の構造的剛性を補強し、加圧力がインサートの上面に比較的均一に伝達されクランピング力が増加されるようにする效果を持つ。 The present invention has a structure in which the clamp and the pressure plate are simply coupled by a single coupling pin, and has the effect of being easy to manufacture and reducing the number of parts without a separate fixing device such as a screw. Moreover, since the front convex part of the clamp which is fragile is reinforced by the bridge part, there is an effect that the service life is increased. The rear end portion of the pressure plate is formed of a vertical flat surface and is prevented from rotating in the clamp, and has an effect of reducing the rotational force applied to the bridge portion. Further, the protruding reinforcing portion reinforces the structural rigidity of the pressure plate, and has an effect that the applied pressure is transmitted to the upper surface of the insert relatively uniformly and the clamping force is increased.
また本発明はインサートの形態に関係なく、クランプやその圧力板の交換によって、同一のツール
ホルダーにいろんな形のインサート装着が可能である。例えば、図1のツール ホルダーでは垂直貫通された中央穴を持ったインサートの場合を例に説明したが、図8及び図9のように中央ディンプルを持ったり、穴がない平らなインサート(300a、300b)がツール ホルダーにクランピングされる場合にも同一の技術思想が適用されることができる。そのような実施例の場合にはクランプ(200a、200b)の前方凸部の長さ及び形に多少違いがあるだけで、同一の加圧板(100)を使って多様な形態のインサート(300a、300b)を同一のポケット構造を持つツール ホルダーに堅固に装着することができる。
In the present invention, various types of inserts can be mounted on the same tool holder by replacing the clamp and its pressure plate regardless of the form of the insert. For example, in the case of the tool holder shown in FIG. 1, the case of an insert having a central hole vertically penetrated has been described as an example, but as shown in FIGS. 8 and 9, a flat insert (300a, The same technical idea can be applied when 300b) is clamped to the tool holder. In such an embodiment, only the length and shape of the front protrusion of the clamp (200a, 200b) are slightly different, and various forms of inserts (300a, 200b) using the same pressure plate (100). 300b) can be securely attached to a tool holder with the same pocket structure.
